Hello all,

I need to collect performance data about long latency load on my Intel nehalem machine.

As my understanding, I should use PEBS to do this in order to get the data address.

Currently, I can only use perf_event on my machine, because I have kernel 2.6.34 installed in my machine.

Is there any examples or guide on how to program the performance counter to collect PEBS event using perf_event ?

The reason why I can only use perf_event for now is that the installation of perfmon2 kernel was always failed.

The sysadmin in my school try to install kernel linux-2.6.18-perfmon2, but he said the boot up was failed.

He has not tried the perfmon2 2.6.30 though.

Thank you,

Besar
